Answer 1

D

Explanation:

Given: Wanda increased her carbohydrate intake from
`215` grams a day to
`415` grams a day.

To find: By what percentage did Wanda increase the amount of carbs she eats daily.

Solution:

Original amount of carbs Wanda takes
`=250` grams.

New amount of carbs Wanda takes
`=415` grams.

Increase in amount of carbs
`=415-250=165` grams.

`\textrm{Percentage increase}=\frac{\textrm{Increase in the amount of carbs taken}}{\textrm{Original amount of carbs taken}}* 100\%`

`\textrm{Percentage increase}=(165)/(250)*100\%`

`\textrm{Percentage increase}=66\%`

So, Wanda increase
`66\%` of carbs she eats daily.

Hence, option D is correct.
